One of the biggest puzzles of modern cosmology is the accelerated expansion of the Universe, which was observed at the beginning of the 21st century. One of the possibilities, how to obtain a model, is to add the cosmological constant into the Einstein equations. Second possibility is to change the theory of gravity. There are many ways, how to do it. We were investigating so called f(R)-theories. General Relativity is one example of these theories for f(R) = R. Here is my talk.

I do trust all the concepts you have presented on your

post. They’re really convincing and will definitely work.

Still, the posts are too quick for novices.

May you please extend them a bit from subsequent time?

Thanks for the post.

Thank You for a comment! I will try …

Hi! I am putting different posts on my blog. Some of them are a basic physics and mathematics, some of them are very advanced. You can ask me precisely, what You want to explain more. Thank You for Your comment.:)
